This research work presents a diagnosis of the organizational culture of the Educational Program of Industrial Engineering of the Technological University of Tecamachalco, according to the findings found and where it can intervene to establish improvement strategies. To carry out the research and based on the literature review, the quantitative method was used through the Competing Values Framework Model as the most appropriate to diagnose the organizational culture in an educational institution, taking into consideration studies carried out in Mexico (García, Hernández, Vargas and Cuevas, December 2012; Sánchez, 2017; Chuc, 2017) and that for its application in a case study it was necessary to determine the validity and reliability of the instrument. In order to understand how an organization will act under different circumstances, it is necessary to know what basic assumptions it has, that is, to inquire into its organizational culture to know "shared values, habits, uses and customs, codes of conduct, work policies, traditions and objectives that are transmitted from one generation to another. " (Chiavenato, 2009, p. 120).

This article presents a study of the generation and management of solid waste in Latin America and aims to show how to create economic value for companies and benefits for society and government, by moving from a linear economic model to a Circular economic model to re-conceive the generation and management of solid waste at the same time, the development of solid waste processing clusters in Latin America. The study begins by identifying the problems currently generated by inefficient solid waste management in Latin America, then quantifying the affectation of these problems for society, and finally, the identification of key factors to re-conceive a system of recovery of solid waste and its processing with the aim of returning its economic value or insert them back into the value chain, through the study of cases in developed countries that have adopted a circular economy model in the management of their waste solid.

In open pit mining, the loading, unloading and hauling system can represent a high percentage of the operating cost. The objective of this document is to provide an overview of the different approaches in the application of simulation models as an alternative applied to open pit mining operations that can help in decision making to optimize resources. It talks about the different types of simulation models that can be applied in mining operations such as stochastic, deterministic and discrete events. The underlying idea of this text is to highlight that with the increase in competitiveness, mining companies are in need of using simulation techniques to reduce costs, time and risks when making decisions, since simulation allows the creation of scenarios that approximate reality. In the end, the document concludes that simulation models are a tool to help in decision-making, for the optimization of resources, increased improvement and efficiency of the processes of loading, transport and unloading in open pit mines.
